Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a radiation image information reading and reproducing device used in a radiation image information recording and reproducing system, which reads and reproduces radiation image information within the same device using the same scanning system. It is something.

(Conventional technology) Certain phosphors are exposed to radiation (X-rays, α-rays, β-rays.

When irradiated with γ-rays, electron beams, ultraviolet rays, etc., a part of this radiation energy is accumulated in the phosphor, and when this phosphor is irradiated with excitation light such as visible light, the phosphor changes depending on the accumulated energy. is known to exhibit stimulated luminescence, and phosphors exhibiting this property are called stimulable phosphors (stimulable phosphors).

Using this stimulable phosphor, radiation image information of a subject such as a human body is partially recorded on a sheet of stimulable phosphor, and this stimulable phosphor sheet is scanned with excitation light such as a laser beam to make it shine. The resulting stimulated luminescent light is generated and photoelectrically read to obtain an image signal, and based on this image signal, the radiation image of the subject is recorded as a visible image on a recording material such as a photographic light-sensitive material, a CRT, etc. The applicant has already proposed a radiation image information recording and reproducing system for outputting radiation image information. (Unexamined Japanese Patent Publication No. 55
-12429, 5B-11395, 55-16
No. 3472.

No. 5B-104645, No. 55-1113340, etc. ) The stimulable phosphor sheet in the above system accumulates and records radiation image information and temporarily carries the recorded image information until it is read by the excitation light scanning, and therefore, the stimulable phosphor sheet is used to temporarily carry radiation image information until it is read by the excitation light scanning. After the process is completed, it is desirable to erase the image information remaining on the sheet and reuse the sheet.

Incidentally, in recent years, various improvements have been made to the radiographic image information recording and reproducing system based on the demand for miniaturizing the entire system as much as possible and reducing manufacturing costs. As one of these improvements, the present applicant has proposed that by using the same sub-scanning means to read and reproduce the image information accumulated and recorded on the stimulable phosphor sheet within the same device, it is possible to The present invention provides a radiation image information reading and reproducing device that can reduce the size of the entire system and reduce manufacturing costs by integrating the existing reading device and reproducing device (Japanese Patent Application No. 82-5283).

(Problems to be Solved by the Invention) As described above, by integrating the reading device and the reproducing device using the same sub-scanning means, the stimulable phosphor sheet is read and an image signal is obtained. Although it is now possible to reproduce and output a radiographic image of a subject based on image signals using an integrated device, there are still many systems in use that obtain X-ray images of a subject using conventional X-ray film. Furthermore, even if the conventional system is replaced with a system using a stimulable phosphor sheet, a large amount of X-ray film on which X-ray transmission images have been recorded in the past is already stored. Furthermore, in recent years, many diagnostic instruments such as CT and US have been used, and there are many films recording images output from these instruments. It is desirable that the image information recorded on these films can be photoelectrically read, subjected to image processing in the same manner as the image signals read from the stimulable phosphor sheet, stored, and reproduced and output.

Conventionally, for the above purpose, it was necessary to use a film reading device that photoelectrically reads the film on which the radiation image is recorded, separately from the system using the stimulable phosphor sheet. Even if only the system using the system was improved and miniaturized, there was a limit to the overall miniaturization and cost reduction.

The present invention not only integrates a reading device that reads image information stored and recorded on a stimulable phosphor sheet to obtain an image signal, and a reproduction device that reproduces and outputs an image based on this image signal, but also records the image information on a film. By integrating a film reading device that reads the image information read by the film reading device, it is possible to reproduce and output images based on the image signals read by this film reading device, making the entire system including the film reading system more compact and reducing manufacturing costs. It is an object of the present invention to provide a radiation image information reading and reproducing device that can reduce the amount of radiation.

Furthermore, if a part of the stimulable phosphor sheet conveyance means, film conveyance means, and recording sheet conveyance means are shared, the system can be further downsized and cost reduced.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic side view showing the outline of a radiation image information reading and reproducing apparatus according to an embodiment of the present invention.

In this apparatus, a stimulable phosphor sheet supply section 10 that removably holds a plurality of cassettes 2 capable of storing stimulable phosphor sheets 1, and a developing section film 91 are placed on a guide plate 92.
By inserting between the guide plate 92 and the light-shielding plate 93, a film supply unit 90 that can supply the film 91 into the device and a recording sheet supply magazine 4 that can store a plurality of recording sheets 3 can be attached and detached. a recording sheet supply section 40 that freely holds the recording sheet, an optical scanning section 20 that scans the stimulable phosphor sheet 1 or the film 91 to read image information, and records the read image information on the recording sheet 3;
It is equipped with an erasing section 30 that erases image information remaining on the stimulable phosphor sheet 1 that has been read by the optical scanning section 20, and an automatic developing section 70 that develops the recording sheet 3 that has been recorded in the optical scanning section 20. .

The inside of this device includes a stimulable phosphor sheet 1 and a recording sheet 4.
Necessary light shielding is provided to prevent exposure to external light.

In this apparatus having the above configuration, a case will first be described in which image information stored and recorded on the stimulable phosphor sheet 1 is read.

A cassette 2 in which the stimulable phosphor sheet 1 held inside is photographed by an external photographing device (not shown) is loaded into the stimulable phosphor sheet supply section 10. In the apparatus of this embodiment, for example, two cassettes 2 can be held by the stimulable phosphor sheet supply section 10. This cassette 2 has a light-shielding property to prevent the sheet from being exposed to external light when recording (photographing) image information by irradiating the stimulable phosphor sheet with radiation. It consists of a cassette main body 2a for storing body sheets and a lid part 2b that can be opened and closed.

This lid portion 2b is closed when the cassette 2 is loaded into the stimulable phosphor sheet supply section 10, but when the stimulable phosphor sheet inside the stimulable phosphor sheet supply section 10 When it is taken out, the lid opening means 11 such as a suction cup opens the lid part 2b as shown in the figure.

The stimulable phosphor sheet supply section 10 has two
Several cassettes are stored parallel to each other in the vertical direction, and a stimulable phosphor sheet 1 is taken out from each cassette 2. Taking out and conveying the stimulable phosphor sheet 1 will be explained by taking as an example the upper cassette 2 of the cassettes 2 held in the cassette 2 .

The illustrated device includes an endless belt, rollers, and guide plates that take out a stimulable phosphor sheet 1 from an arbitrary cassette 2 in a stimulable phosphor sheet supply section 10 and convey it to an optical scanning section 20 and an erasing section 30 in this order. A stimulable phosphor sheet conveying means 50 is provided, and a part of this stimulable phosphor sheet conveying means 50 is provided with a stimulable phosphor sheet conveying means 50 that can carry any one of the cassettes 2 in the stimulable phosphor sheet supply section 10. A movable conveyance section 51 that can move up and down is formed so as to selectively come into contact with the end of the conveyance section 51 . FIG. 2 is a partially enlarged perspective view of this moving conveyance section. When taking out the stimulable phosphor sheet 1 from the uppermost cassette 2 in the stimulable phosphor sheet supply section 10 as described above, the movable conveyance section 51 is located at the uppermost position as shown in the figure. and is adjacent to the upper cassette 2.

The suction means 12 enters into the cassette 2 with the lid 2b open, sucks the stimulable phosphor sheet 1 inside the cassette 2, takes it out, and transfers it to the belt conveyor 51d of the movable conveyance section 51.
, passed to roller 51f', and then passed to belt conveyor 5
1d and the roller 51e.

The stimulable phosphor sheet 1 is held in the cassette 2 so that the front surface on which the stimulable phosphor layer is formed faces down. The stimulable phosphor sheet 1 taken out from the cassette 2 in this way is conveyed in the direction of arrow A1 by rollers 51a and 51b at the position indicated by the solid line by the movable guide plate 51c of the movable conveyance unit 51, and then the stimulable phosphor sheet 1 The sheet is transported by the sheet transport means 50 in the directions of arrows A2 to A4 and is carried into the optical scanning section 20.

The optical scanning unit 20 scans the stimulable phosphor sheet 1 on which image information is accumulated and recorded with a laser beam 21, and detects the light emitted from the sheet 1 excited by the scanning. It operates by photoelectrically reading the stimulated luminescent light with a stimulated luminescent light detecting means 22 such as a photomultiplier to generate an electrical image signal for outputting a visible image.

In the figure, 23 is an example of a He-Ne laser light source, 24 is a light deflector such as a galvanometer mirror, and 25 is a light guide 22a of a photoelectric reading means (the light guide 22a is a photodetector 22b such as a photomultiplier because the stimulated luminescence light is not totally reflected.
It is a reflecting mirror that reflects the light toward the Note that the optical modulator 2B such as an AOM uses a laser beam 21
When scanning the stimulable phosphor sheet 1, the operation is stopped.

The stimulable phosphor sheet 1 carried into the optical scanning section 20 is transported in the direction of arrow A5 by the stimulable phosphor sheet transport means 50, and the stimulable phosphor sheet 1 is transported by the laser beam 21 deflected approximately perpendicular to this transport direction. The entire surface is scanned two-dimensionally to generate stimulated luminescence light, which is detected by the photodetector 22b via the light guide 22a. In the photodetector 22b, the stimulated luminescent light is converted into an electrical signal, and the obtained electrical signal is sent to the image information processing circuit 27.
After being sent to the computer and subjected to image processing, it is stored in the memory 29. In this embodiment, the stimulable phosphor sheet conveying means 50 in the optical scanning section 20 serves as a sub-scanning means.

In addition, when reading radiation image information, reading to obtain image signals for visible image output as explained above (main reading)
Prior to this, pre-reading is performed to read the outline of the radiation image information stored and recorded on the stimulable phosphor sheet, and based on the image information obtained by this pre-reading, the reading conditions etc. for performing the main reading are determined. However, a method of performing the main reading according to the reading conditions is known.

As a method for performing such pre-reading, for example, the stimulable phosphor sheet 1 is scanned using excitation light with an energy lower than that of the laser beam (excitation light) used for the above-mentioned main reading, and the luminance emitted by this scanning is There is a method (for example, see Japanese Unexamined Patent Publication No. 87240/1983) in which the stimulated luminescence light is read using a stimulated luminescence detection means.

The optical scanning section in the present invention may be a section that performs both main reading and pre-reading in addition to the above-mentioned section that performs only main reading. For example, the stimulable phosphor sheet 1 is conveyed in the direction of arrow A5 to perform pre-reading, then the stimulable phosphor sheet 1 is conveyed back in the direction of arrow A6 by switchback, returned to the reading start position, and then read in the direction of arrow A5 again. What is necessary is to carry it and read it. Note that the optical members disposed in the optical scanning section are not limited to those described above; for example, a long photomultiplier is disposed along the main scanning line as a stimulated luminescence light detection means, and Exhaustive luminescence light may be detected (see Japanese Patent Application No. 156255/1984) As described above, the stimulable phosphor sheet 1 whose image information has been read in the light scanning unit 20 is a stimulable phosphor sheet. The paper is transported by the transport means 50 toward the erasing section 30 in the direction of the arrow AT force. Note that a first sorting means 52 and a second sorting means 111 are provided between the optical scanning section 20 and the erasing section 30, but when the stimulable phosphor sheet 1 is conveyed, The first and second sorting means 52 and 111 are located at the positions indicated by solid lines in the figure and guide the stimulable phosphor sheet 1 to the erasing section 30.

The erasing unit 30 erases the stimulable phosphor sheet 1 after the reading is completed.
This is to erase the radiation image information that is about to remain in the stimulable phosphor (to release the radiation energy remaining in the stimulable phosphor). That is, some of the radiation image information accumulated and recorded on the stimulable phosphor sheet 1 still remains on the stimulable phosphor sheet 1 after reading, and in order to reuse this stimulable phosphor sheet 1, This residual image information is erased in the eraser 30. Erasing unit 3 in this embodiment

are provided, and the stimulable phosphor sheet 1 is transported in the direction of arrow A8 and is irradiated with light by these erasing light sources 31, so that the residual radiation energy on the stimulable phosphor sheet 1 is emitted. Note that the erasing method in the erasing section 30 may be any known method, and erasing may be performed using heating or a combination of light irradiation and heating.

The stimulable phosphor sheet 1 that has been erased in the erasing section 30 is moved by the stimulable phosphor sheet conveying means 50 in the direction of arrow A.

Next, a case will be described in which image information recorded on the developed film 91 on which a radiation image is recorded is read.

Developed film 91 recorded and developed with an external recording device and developing device (not shown) and on which radiation image information is recorded.
is supplied into this apparatus from a film supply section 90. In the apparatus of this embodiment, the film 91 is supplied one by one from outside the apparatus. For example, the recording sheet supply magazine 4 and the recording sheet supply section 4
Similarly, a plurality of films 91 are stored in a magazine,
The stored magazine may be loaded into the apparatus, and the films 91 may be taken out one by one from the loaded magazine.

The film 91 inserted from the film supply section 90 is transferred to rollers 94a and 94 by the film transport means 100.
b, and arrows Bl, B2. It is transported in the direction of B3 and into the optical scanning section 20.

The film 91 conveyed to the optical scanning unit 20 is conveyed in the direction of arrow B4 by the film conveyance means 100, and the entire surface of the film is two-dimensionally scanned by the laser beam 21 which is deflected approximately perpendicular to this conveyance direction. The laser beam 21 whose intensity is modulated according to the image information recorded on the laser beam 91 is photoelectrically read by a light beam detection means 28 such as a long photomultiplier to obtain an image signal.

This light beam detection means 28 is not a long photomultiplier, but may be a combination of a light guide and a photomultiplier, for example, similar to the stimulated emission light detection means 22, but is sensitive to the wavelength of the laser beam 21. Consists of optical members.

When scanning the film 9 with the laser beam 21, the light modulator 2
B has stopped operating. The image signal obtained by the light beam detection means 28 is sent to the image information processing circuit 27 and subjected to image processing. In the optical scanning section 20, the film conveyance means 100 is common to the stimulable phosphor sheet conveyance means 50, and this common portion serves as a sub-scanning means.

The film 91 whose image information has been read in the optical scanning section 20 as described above is transported by the film transport means 100 in the direction of the arrow BT+B towards the film discharge section 110. A first sorting means 52 and a second sorting means 111 are provided in the middle of this conveyance, but when the film 91 is conveyed, the first sorting means 52 is indicated by a solid line in the figure. The second sorting means 111 is located at the position shown by the broken line in the figure, and the film 91 is transferred to the roller 112.
a, LL2b, and the film 91 is guided between rollers 1 and LL2b.
It passes between 12a and 112b, is discharged to the outside of the device, and is stored in a tray 114.

The case where an image is reproduced on the recording sheet 3 based on the image signal read from the stimulable phosphor sheet 1 or the film 91 as described above will be described next.

One recording sheet 3 is taken out from the magazine 4 in the recording sheet supply section 40 by the suction means 41 and delivered to the nearby recording sheet conveying means 60. This recording sheet conveying means 60 receives and transports the recording sheet 3 to the optical scanning section 20, and also conveys the recording sheet 3 that has passed through the optical scanning section 20.
A portion thereof is shared by the stimulable phosphor sheet conveying means 50 and the film conveying means 100. The recording sheet 3 is conveyed in the directions of arrows cl and c2 by the recording sheet conveying means 60, and is carried into the optical scanning section 20, and is moved inside the optical scanning section 20 in the direction of arrow C.
The image information read from the stimulable phosphor sheet 1 or the film 91 is recorded while being conveyed in three directions.

When the recording sheet 3 is conveyed, the optical scanning section 20 reads the stimulable phosphor sheet 1 or the film 91 described above, performs image processing, and performs optical modulation according to the image information stored in the memory 29. The device 26 is driven, and the stimulated luminescence light detection means 22 and the light beam detection means 2
8 is stopped. The recording sheet 3 is modulated by the optical modulator 26 and then scanned by the laser beam 21, which is the recording light, deflected by the optical deflector 24.
The image information recorded on the stimulable phosphor sheet 1 or film 91 is reproduced over the entire surface.

The recording sheet 3 on which the image information has been reproduced in the optical scanning section 20 is moved by the recording sheet conveying means 80 to arrows CT and C8.
direction and is transported to the developing section 70. At this time, the first sorting means 52 rotates to the position shown by the broken line in the figure and guides the recording sheet 3 to the developing section 70.

In the developing section 70, the recording sheet 3 is placed in a developing zone 71.
．． Fusing zone 72. Washing zone 73. The sheets are sequentially sent to a drying zone 74, subjected to development processing, and stored in a tray 75.

As described above, in the apparatus of this embodiment, the optical scanning section 20 uses the main scanning means and the sub-scanning means in common to read image information on the stimulable phosphor sheet, read image information on the film, and read image information on the recording sheet. Since information can be reproduced at the same time, the entire system including film reading can be downsized, and manufacturing costs can be reduced. Furthermore, in the above-described embodiment, the stimulable phosphor sheet supply section 10 can hold a plurality of cassettes, so even while reading or playback is being performed in the optical scanning section, a cassette that has already been photographed can be inserted. This is convenient because it can be kept on standby.

Note that the movable conveying section 5 of the stimulable phosphor sheet conveying means 50
1 is an arbitrary cassette 2 of the stimulable phosphor sheet supply section 10;
As the movable conveyance section 51 moves, the upper and lower rollers 53a, 51b, 54a, 54b,
55a and 55b also move vertically to keep the distance between each roller always smaller than the length of the stimulable phosphor sheet.

It looks like this. Furthermore, in the embodiment described above, 1
An example has been described in which the read image information is recorded on one recording sheet immediately after reading one stimulable phosphor sheet or one film. In the optical scanning section, first, multiple stimulable phosphor sheets are read continuously, all the read image information is temporarily stored, and then image information is continuously recorded on multiple recording sheets. You may also do this. Further, without having to reproduce all the read image information as a hard copy on a recording sheet, it is possible to display the image information once on a CRT display device or the like and reproduce only the necessary images as a hard copy on the recording sheet.

By the way, as mentioned above, stimulable phosphor sheets and films are first photographed using an external photographing device.
When reproducing the read image information, it is necessary to display information about the subject (subject), for example, information unique to the subject such as name, gender, date of photographing, and body part to be photographed together with the image information.

Conventionally, this ID information is input into an ID card or the like using a special ID input means such as an ID terminal at the time of shooting, and when the image information is played back, the input information is transmitted to the playback device and then added to the image information and replayed. It is designed to be displayed on the main surface. However, in that case, a special input means is required, which makes the entire system complicated and makes input operations troublesome. Since the device of the present invention is intended to simplify the entire system, it is desirable to read the ID information and display it on the playback surface without using a complicated and large-scale device such as an ID terminal. For example, by using a photographing instruction sheet that is usually created for each subject at the time of photographing, this reading and reproducing device is equipped with an image pickup tube or solid-state image sensor that reads the part of the instruction sheet in which the subject's ID information is written, and these The ID information may be read as an image signal using a reading means, and this image signal may be temporarily stored and reproduced on the recording sheet together with separately read radiation image information.

Next, another device of the present invention will be explained with reference to FIG. Note that the same parts as in the apparatus according to the above-mentioned embodiments are given the same numbers, and the explanation thereof will be omitted.

In the illustrated apparatus, the stimulable phosphor sheet supply section 10' holds only one cassette 2, and the stimulable phosphor sheet 1 is taken out from the cassette 2 in the stimulable phosphor sheet supply section 10'. When the cassette 2 is empty, it is immediately placed in the stimulable phosphor sheet storage section 120.
is loaded into. The stimulable phosphor sheet 1 taken out from the cassette 2 is sequentially conveyed by the stimulable phosphor sheet conveying means 50 to the optical scanning section 20 and the erasing section 30, where image information is read and erased. The stimulable phosphor sheet 1 that has been erased is carried by the stimulable phosphor sheet conveying means 5o into the cassette 2 that is waiting in an empty state in the sheet storage section 120, and is taken out of the apparatus and used for new shooting. It becomes something that can be offered to people.

Further, the cassette 2 is also used to store the developing section film 91. The aforementioned stimulable phosphor sheet supply section 10'
also serves as a film supply section 90', and when the film 91 is taken out from the cassette 2 in this film supply section 90', the cassette 2 is empty as in the case of reading the stimulable phosphor sheet 1 described above. Film storage section 140 that also serves as stimulable phosphor sheet storage section 120
is loaded into. Film 9 taken out from cassette 2
1 is sent to the optical scanning unit 20 by the film transport means 100 which also serves as the stimulable phosphor sheet transport means 50, and the image information is read. The film 91 that has been read is carried by the film transport means 100 into the cassette 2 which is waiting in an empty state in the film storage section 140, and is taken out of the apparatus. Note that when the film 91 is transported, read, and stored, the erasing light source 31 of the erasing section 30 is not needed and is turned off.

From the magazine 4 in the recording sheet supply section 40, the optical scanning section 2
0, each time reading of the stimulable phosphor sheet 1 or film 91 is completed, the recording sheets 3 are taken out one by one and sent to the optical scanning section 20 by the recording sheet conveying means 60. After the image information read from the stimulable phosphor sheet 1 or film 91 is recorded in the optical scanning unit 20, the recording sheet 3 is transferred to the recording sheet storage unit 80 that removably holds the recording sheet storage magazine 5. transported. That is, the roller 61, which is a part of the recording sheet conveyance means 60, moves between the position indicated by a solid line and the position indicated by a broken line in the figure, thereby moving the conveyance path of the stimulable phosphor sheet 1, the film 91, and the recording sheet 3. When the stimulable phosphor sheet 1 or the film 91 is carried out from the optical scanning unit 20, the roller 6 is at the position shown by the solid line in the figure, and the stimulable phosphor sheet 1 or the film 91 is switched. 91 toward the erasing section 30, but the optical scanning section 2
When the recording sheet 3 is carried out from the recording sheet storage section 80, the roller 61 moves to the position indicated by the broken line in the figure and guides the recording sheet 3 to the recording sheet storage section 80. The recording sheet storage magazine 5 containing the recording sheets 3 is transported to an external automatic developing machine as appropriate.

In this apparatus, instead of providing six recording sheet storage sections 80, an automatic developing section 70' may be provided, and the recording sheet 3 taken out from the optical scanning section 20 may be directly conveyed to the automatic developing section 70'. In that case, the automatic developing section 70' is connected to the optical scanning section 2.
It is preferable to arrange it below 0 because the installation space for the entire device can be reduced.

Further, the automatic developing section may be integrated with other parts or separated via a recording sheet conveying means, but as shown in the figure, it may be integrated with other parts in the same housing 130. One advantage is that it is easy to control temperature etc. Furthermore, the cassette loaded into the stimulable phosphor sheet storage section 120 does not necessarily have to be the cassette taken out from the stimulable phosphor sheet supply section 10'; instead, a separate empty cassette may be loaded into the sheet storage section 120. You may also do so. Also, the stimulable phosphor sheet supply section 10' and the storage section 1
The magazine 20 does not necessarily have to be equipped with a cassette, but can accommodate a plurality of stimulable phosphor sheets.

A tray or the like may be loaded. When a tray is used in the sheet storage section 120, the erasing section 30 does not necessarily need to be provided, and the tray containing the stimulable phosphor sheet may be taken out and erased separately. Furthermore, in any of the embodiments, the arrangement and specific structures of the stimulable phosphor sheet supply section, film supply section, recording sheet supply section, optical scanning section, erasing section, etc. are not limited to those described above. . For example, in the optical scanning section, at least the sub-scanning means for the stimulable phosphor sheet, the film, and the recording sheet may be used in common; The scanning means may be provided independently, and the scanning means may be provided independently.
For recording, the optical deflector of the bidirectional scanning means is shared, and the reading light source,
A recording light source may be provided separately and switched by a mirror or the like.

In addition to the usual silver salt film, heat-developable photosensitive materials, instant films, heat-sensitive sheets, etc. may be used as the recording sheet. In this case, the developing section used has a configuration that is compatible with the recording sheet used.

(Effects of the Invention) As explained above, according to the radiation image information reading and reproducing apparatus of the present invention, image information stored and recorded on stimulable phosphor sheets, which were conventionally provided independently and separately, By using the same sub-scanning means, the reading of the image and the reproduction and recording of the image are integrated, and the reading of the image recorded on the film can also be performed using the same sub-scanning means. The entire system including the system can be downsized and manufacturing costs can be reduced.

In addition, only one optical deflector and light source for the main scanning means can be provided for reading and reproduction, and a stimulable phosphor sheet,
Since some of the transport means for the film and the recording sheet can be shared, it is possible to greatly reduce manufacturing costs.
